Great news!
If you are editing a page in Percussion (such as editing or dragging n dropping the widget) and somehow your main navigation’s dropdown gets in your way… there’s a way to prevent. I found Percussion’s class ‘.perc-locked’ so I decided to add ‘.perc-locked .dropdown {display:none !important;}’ in my main css file and uploaded to Percussion. It worked perfect. This will not affect the real live site which is nice.
Here is the screenshot attached… of before / after
